Multifunctional anaesthetization system with hot link technology of soft type bronchoscope

Abstract

The invention discloses a multifunctional anaesthetization system with a hot link technology of a soft type bronchoscope. By adopting a method of staged heating of air and an anaesthetic by an electric heating element, compressed air from an air pump and a liquid medicine from a medicine bottle both can keep a constant temperature above an airway temperature before entering the airway of a patientand are properly cooled through a working passage of the bronchoscope in a room-temperature state, thus, a temperature of the air and the anesthetic entering the airway of the patient is equal to orslightly higher than a human normal body temperature, and thus, stimulation caused by difference of temperatures between the sprayed anesthetic and the airway of the patient is eliminated. Meanwhile,according to the system, a control handle and a liquid medicine temporary storage are redesigned; a pump head bottle with a constant-temperature heating function, a waste liquid temporary storage, a counterflow preventing interface and a multichannel wireless control transmitting and receiving device are additionally arranged. According to the system disclosed by the invention, sufferings of the patient during bronchoscope diagnosis and treatment can be substantially reduced, the problem that the patient is prone to feelings of asphyxia and agony during diagnosis and treatment is avoided, andthe system has a great clinical application value.

Description

technical field [0001] The invention relates to an anesthesia system for bronchoscope operation, in particular to a multifunctional anesthesia system suitable for flexible bronchoscope. Background technique [0002] Flexible bronchoscope (fiber type or electronic type) is currently the most important device for the diagnosis and treatment of lung diseases widely used clinically. It has a history of more than 50 years since it was invented in the 1960s. It is widely used in countries all over the world. For more than 50 years, for the anesthesia of the airway mucosa during operation, most hospitals have followed the anesthesia method used since the birth of the bronchoscope—the applicant calls it "traditional anesthesia method". In this method of anesthesia, the assistant uses a syringe to extract the local anesthetic in advance, inject it into the working channel of the bronchoscope, and then use the air reserved in the syringe to flush the anesthetic in the working channel...

AI Technical Summary

Problems solved by technology

There are many defects in the traditional anesthesia method: (1) the required anesthesia dose is large, the anesthesia range is small, and the effect is not good; (2) there are dead ends in anesthesia; (3) at least two people are required to complete the operation, and the result is the operation steps Many, time-consuming and labor-intensive, and there are also problems of poor coordination

(4) The blood and secretions attached to the objective lens of the bronchoscope cannot be effectively removed during the operation, resulting in unclear vision and seriously affecting the accuracy of diagnosis and treatment

(5) Medical staff operating bronchoscopes are often exposed to a high risk of biological infection

The cooling characteristics of the old anesthesia system make its application in winter not only fail to relieve the patient's pain, but increase the pain. Therefore, the use of this anesthesia system will be significantly limited in winter or other colder periods.

(2) The wireless signal output of the old version of anesthesia system is single-channel, which can only control the anesthesia system to perform one function, and there are various clinical diagnosis and treatment tasks. Therefore, the role of the old version of anesthesia system to reduce the labor intensity of staff is very limited

(3) The unreasonable design of the position of the one-way valve in the liquid temporary register of the old version of anesthesia system cannot effectively prevent the possible bacteria-carrying drug liquid from flowing backward into the local anesthetic drug bottle, resulting in bacterial contamination of the drug liquid in the drug bottle, thereby increasing the patient's exposure to pathogens risk of microbial infection

(4) Due to the design flaws of the liquid temporary storage device itself and the subsequent gas circuit design of the old version of the anesthesia system, the liquid medicine in it will flow out of the anesthesia system in a short period of time and enter the working channel of the bronchoscope, that is, The time that the liquid medicine stays in the register is uncontrollable. Often when a fixed-point anesthesia is needed, it is discovered that the anesthetic has run out and anesthesia cannot be performed.

This defect will not only increase the consumption of anesthetics, but also seriously affect the effect and efficiency of anesthesia

(5) The old version of the anesthesia system did not design a dedicated bronchoscope working channel interface, but directly used the plastic straight-through connector on the old infusion set to connect with the bronchoscope working channel. This connection made the plastic connector and the outlet of the anesthesia system in the extension line As a result, the silicone tube connecting the two is easily bent at a right angle, and the tube at the bend is completely blocked, and the drug solution cannot pass through, resulting in failure of anesthesia

Therefore, you must be very careful when using the old version of anesthesia system, and check the silicone tube at any time, because the failure of anesthesia often occurs because the silicone tube is not found in time to bend and lock.

[0004] These defects in the old version of the anesthesia system have seriously affected the clinical use environment and effect of the anesthesia system, failing to achieve the original purpose of developing the anesthesia system
